I am trying to pass data array object to html list dynamically.
<div class="sidebar" *ngFor="let q of obj">
<h4>Approvals</h4>
<ul *ngFor="let c of q.element">
<li>
<a href="#"><img class="sideico" src="../../../assets/images/icons/BRIA.svg" />{{c}}</a></li>
</ul>
</div>
In ts file
obj = [
{
"element" : "Timesheet",
"icon": "../../../assets/images/icons/BRIA.svg"
},
{
"element" : "Timesheet",
"icon": "../../../assets/images/icons/BRIA.svg"
}
];
I am new in Angular. What is wrong?
Demo You need just one loop
<div class="sidebar" >
<h4>Approvals</h4>
<ul *ngFor="let q of obj">
<li>
<a href="#"><img class="sideico" [src]="q.icon | safe : 'url'" />{{q.element}}</a>
</li>
</ul>
</div>
and use custom safe pipe to bind
import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml, SafeStyle, SafeScript, SafeUrl, SafeResourceUrl } from '@angular/platform-browser';
@Pipe({
name: 'safe'
})
export class SafePipe implements PipeTransform {
constructor(protected sanitizer: DomSanitizer) {}
public transform(value: any, type: string): SafeHtml | SafeStyle | SafeScript | SafeUrl | SafeResourceUrl {
switch (type) {
case 'html': return this.sanitizer.bypassSecurityTrustHtml(value);
case 'style': return this.sanitizer.bypassSecurityTrustStyle(value);
case 'script': return this.sanitizer.bypassSecurityTrustScript(value);
case 'url': return this.sanitizer.bypassSecurityTrustUrl(value);
case 'resourceUrl': return this.sanitizer.bypassSecurityTrustResourceUrl(value);
default: throw new Error(`Invalid safe type specified: ${type}`);
}
}
}
